摘要
北京地铁14号线某盾构区间始发端洞门凿除施工中,针对安全隐患多,难度大等施工风险,总结了富水软弱地层洞门围护结构凿除的施工工艺,减少或避免了洞门处土体滑移坍塌等现象,降低了凿除人员安全险险,提高了施工效率。
There are many potential safety hazards and high construction difficulty in launching opening chiseling construction of a shield interval of Beijing subway line 14. This paper summarized the construction process of opening enclosure structure chiseling in rich-water weak straturn, successfully reducing or avoiding soil slippage and collapse at opening, alleviating the chiseling workers＇ safety risk and improving construction efficiency_
